The graticle of device, can also be used simultaneously, and the graticle do not lacked of proper care as light path is used.
The utility model provides a kind of graticle, including substrate, and graduation ten is carved with the upper surface of substrate center
Word, the graduation cross is the structure to lower recess, and the recess of the graduation cross is provided with conversion coating, the conversion
Infrared light can be converted into below visible ray, the substrate and be provided with light at 15~25cm of its lower surface position by coating
Source.
Optionally, the distance of substrate lower surface described in the light source distance is 20cm.
Optionally, the light source is incandescent lamp, and the light source can provide visible ray light wave and infrared waves simultaneously.
Optionally, the substrate is made up of ZnS materials.
Optionally, the substrate is cylindrical base.
The utility model has advantages below and beneficial effect：The utility model provides a kind of graticle, and being both adapted to do can
See the graticle of optical tests instrument, the graticle for making infrared test instrument is adapted to again, can also be used simultaneously, is not lost as light path
The graticle of tune is used, and it both goes for visible light wave range, is applied to infrared band again, so, same graticle is set
Meter can both meet the test of visible ray and infrared light two waveband instrument, reduce the complexity of test structure, and graticle is not yet
By temperature and vibration effect light path can be caused to lack of proper care；For visible ray and infrared light tester, the graticle can be seen
Observe, apply to broadband graticle.

It is indirectly connected to, can is the connection of two element internals.For the ordinary skill in the art, can be according to specific feelings
Condition understands concrete meaning of the above-mentioned term in the utility model.
The utility model is further described with specific embodiment below with reference to accompanying drawings.
As shown in Figure 1：A kind of graticle that the utility model embodiment is provided, including substrate 100, the upper surface of substrate 100
Graduation cross 200 is carved with center, and graduation cross 200 is the structure to lower recess, and the recess of graduation cross is provided with
Infrared light can be converted into visible ray by conversion coating, conversion coating, meanwhile, graduation cross can be by fine groove or other marks
Property groove, image replace, groove or image recess can fill conversion coating as needed, and the conversion coating is by conversion material
Material is constituted, and light source is provided with 15~25cm of its lower surface position below substrate, light source is incandescent lamp, using incandescent lamp
As the lighting source of graticle, the light source can provide visible ray light wave and infrared waves simultaneously；The graduation ten of the graticle
The recess filling up-conversion of word, can be converted into visible ray by infrared light；Open after graticle light source, for infrared survey
For examination or optical viewer, graticle substrate is bright, and graduation cross is dark, is come for visible optical tests or optical viewer
Say, graticle substrate is dark, and graduation cross is bright；For visible ray and infrared light tester, the graticle can be with
It was observed that, therefore broadband graticle is applied to, both it has been adapted to the graticle for making visible ray tester, has been adapted to do infrared again
The graticle of tester, can also be used simultaneously, and the graticle do not lacked of proper care as light path is used.
As the preferred embodiment of above-described embodiment, the distance of light source distance substrate lower surface is 20cm.
As the preferred embodiment of above-described embodiment, substrate is made up of ZnS materials.
As the preferred embodiment of above-described embodiment, substrate is cylindrical base.
As shown in Fig. 2 being described in further details below so that plain shaft parallelism is tested as an example to patent of the present invention：
(1) substrate of graticle uses ZnS materials, and graduation cross or other grooves, figure are carved with above；
(2) the graduation cross depression of graticle is back to incandescent light source, and filling up-conversion, when running into infrared light
When, sightless infrared light will be changed into visible ray by the material；
(3) graticle 20cm or so is left, with Uniform Illumination graticle as the lighting source of graticle using incandescent lamp
It is advisable, why using incandescent light source, is primarily due to incandescent lamp wavelength and enriches, visible ray light wave can be provided simultaneously and red
Outer light wave；
(4) graticle is arranged on the focal plane of photoelectric collimator, after light source is opened, infrared light ZnS substrates illuminate
Graticle, because graticle is on photoelectric collimator focal plane, therefore, photoelectric collimator is defeated in directional light form by the picture of graticle
Go out to thermal infrared imager and visible light camera, structural representation is as shown in Figure 2.For thermal infrared imager and visible light camera
For, the graticle of photoelectric collimator is provided for an infinity target；
(5) graticle is observed with visible light camera, because graticle substrate is ZnS, it is impossible to pass through visible ray, therefore,
Substrate is dark, and substrate can pass through infrared light, and infrared light excites up-conversion in graduation cross recessed groove, and sending can
See light, can be observed by visible light camera, therefore, it is seen that light video camera is observed that graduation cross is bright；
(6) graticle is observed with thermal infrared imager again, graticle substrate is bright, and graduation cross is dark；
(7) the graduation cross of the graticle, can be observed for visible ray and infrared light tester, then for visible
With infrared common optical axis system, the collimation test of visible, infrared optical axis can be carried out, as shown in Fig. 2 first by infrared heat
As instrument aims at graduation cross, then read from visible light camera the deviation of visible light collimation mirror and graduation cross, you can see optical axis
With the parallel misalignment of infrared optical axis, so, two sets of light paths share one piece of graticle, can accomplish that light path is not lacked of proper care.
Finally it should be noted that：Above-described each embodiment is merely to illustrate the technical solution of the utility model, rather than
It is limited；Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art
It should be understood that：It can still modify to the technical scheme described in previous embodiment, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or substitutions, the essence of appropriate technical solution is departed from the utility model
The scope of each embodiment technical scheme.
